概念格在基础地理本体层次构建中的应用

Application of concept lattice in the hierarchies construction of fundamental geographic information ontology

本文通过研究基础地理信息中概念间的语义层次来改进现有分类标准。文中分析了基础地理信息中存在的三种概念间的层次关系(Hierarchy):a-kind-of、a-part-of和appertaining-to;重点介绍了使用概念格的思想获取a-kind-of(上下位)关系的方法,并通过推理得到了基础地理信息概念的语义体系,分析实验结果表明了概念格方法建立本体层次的有效性。

This paper researched on the semantic hierarchy in the fundamental geographic information so as to improve the existed classification standard. Firstly, this paper analyzed primarily the three kinds of hierarchy relations existed in the fundamental geographic information system- ＇ a-kind-of＇ , ＇ a-part-of＇ and ＇ appertaining-to＇ . Secondly, it focused on how to identify the ＇ a-kind-of＇ relation with the theory of concept lattice. At last, reasoning was used to build the semantic system for the fundamental geographic information concepts, and the analysis to the experiment result illustrated the efficiency of concept lattice in building hierarchy.
